Summary of "HTML & CSS Full Course: Beginners to Pro 2024 | 3 Mini Projects Included 🔥 Web Development Course"

HTML (HyperText Markup Language) is a markup language, not a programming language.
It is used to structure web pages.
Basic HTML structure includes tags like <html>, <head>, <body>.
Tags have opening and closing parts, e.g., <h1>...</h1>.
Elements consist of opening tag, content, and closing tag.
Headings (<h1> to <h6>) and paragraphs (<p>) are fundamental tags.
Line breaks (<br>) create new lines within paragraphs without starting a new paragraph.
Images are inserted with <img> tag using attributes src (source) and alt (alternative text).
Anchor tags <a> create hyperlinks with href attribute; can open links in new tabs using target="_blank".
Boilerplate code for HTML can be generated quickly using shortcuts in VS Code (! + Enter).
The <head> section contains metadata like the page <title>.

CSS is used to style HTML elements and make web pages visually appealing.
Three types of CSS:
- Inline CSS: Using style attribute inside HTML tags.
- Internal CSS: Using <style> tag inside <head>.
- External CSS: Linking an external .css file.
Common CSS properties:
- color, background-color, font-family, font-size, text-align, width, height, margin, padding, border.
CSS syntax: selector { property: value; }
CSS units: pixels (px), percentages (%).
The difference between margin (outside spacing) and padding (inside spacing).
CSS Box Model: content, padding, border, margin.
CSS selectors: element selectors, class selectors (.), ID selectors (#).
Classes can be reused; IDs are unique per page.

<div> tags are containers to group elements.
Divs can be styled with CSS for layout and design.
Width and height can be set in pixels or percentages.
Using display: flex on parent containers to arrange child divs side by side.
Flexbox properties:
- justify-content: controls horizontal alignment.
- align-items: controls vertical alignment.
Nesting divs for complex layouts.
Using IDs and classes to style individual or groups of divs.

Squares and rectangles: set equal or different width and height.
Circles: use border-radius: 50%.
Diamonds: rotate squares by 45 degrees using transform: rotate(45deg).
Managing size and positioning of shapes with CSS properties like margin, padding, and transform: translate().
Grouping shapes inside containers for better layout control.

Cards are containers with images and text.
Setting card size with height and width.
Adding borders and border-radius for rounded corners.
Positioning cards using:
- Flexbox for horizontal alignment.
- position: absolute with top, left, and transform: translate(-50%, -50%) for centering.
Using z-index to control stacking order of overlapping cards.
Rotating cards using transform: rotate(deg) for visual effect.
Handling image sizing inside cards:
- Use width and height properties.
- Use object-fit: cover to maintain aspect ratio and prevent distortion.
Using overflow hidden on cards to clip overflowing images.
Adding multiple cards with different sizes, colors, and stacking order.
